Relevance – Adding active power to prosthetic knee unit may improve function and reduce overuse injuries in persons with transfemoral amputation (TFA). – Servicemembers with TFA are often young and motivated to perform at high functional levels.

Assessment of transfemoral amputees using C-Leg and Power Knee for ascending and descending inclines and steps. J Rehabil Res Dev. 2012;49(6):831–42. http://dx.doi.org/10.1682/JRRD.2010.12.0234 Slideshow Project DOI:10.1682/JRRD.2010.12.0234JSP Results Knee power generated by nondisabled limb during stair ascent was significantly greater for C-Leg than PK. Knee power generated by prosthetic knee unit was significantly greater with PK. Although PK reduced power required from nondisabled knee during stair climbing, it did not appear superior to C-Leg for other tasks.

However, certain limitations still require improvement.
